I finally recieved a DMS4 SE PRO from modchip dot com, after a month of shipping time. After installing it 6 times I still get nothing but black screen. The DVD will spin up, the laser will seek for a second, then nothing. The screen stays black the enitre time, no logo, no sound, nothing. I have made the BIOS wires as short as possible, with fairly heavy power and ground lines. I don't think there are any shorts, as I can disconnect the power wire, and the PS2 (V14) will boot normally. In fact I can connect the power line after it has booted and it still functions properly, it just won't recognise the chip. I'm convinced that it is a bad chip, however I'm open to any suggestions. I'd like to try to get modchip dot com to replace it, but their customer service seems a bit lacking. Has anybody had any success returning anything to them? Does anybody have their address? Has anybody else had an experiece with the DMS4 like this? I've read some posts on another forum where people described the same behavior. I just want it to work right!
